Hated rivals setting aside differences, however briefly, in order to protect the world from a common enemy. The combined forces of the anomalous world can defeat even a deity.

The Foundation's methods are not always correct. During a crisis, the Foundation is forced to take actions that they would not under less threatening circumstances: COTBG's cooperation and reassembly (allying with other factions), MC&D's funding (accepting anomalous resources from them that the SCPF can’t obtain otherwise), Serpent's Hand's use of the Wanderer's Library, Chaos Insurgency's weaponisation (using anomalies in the war) and Global Occult Coalition's destruction (killing an anomaly when it becomes too much of a threat).

A ritual that switches a set area on Earth with that from an alternate reality, resulting in many strange, whimsical and sometimes hellish alien landscapes (photomanipulations for stronger imagery). As it is easy to perform and can be done from anywhere (all that is required is accurately drawing a specific set of symbols with a small amount of reality bender blood), the anomaly is classified Keter at first.

The COTBG learnt from ancient scriptures that the place holds the Right Hand of Mekhane, a crucial and powerful fragment of their god. The Foundation obtained this information from a raid on a COTBG sect while they were performing the ritual, and then the knowledge was leaked to other enemy GOI as well. (Here, recovered GOI formats are used to show the perspectives and motives of the groups) The Chaos Insurgency wants to weaponise it, MC&D wants to sell it, and the Global Occult Coalition was eventually called in to help the Foundation contain it, but in reality they want it destroyed. Each landscape iteration seems to bring the world closer to an ‘final destination’, as the landscapes become increasingly alien and display more of the end anomaly’s influence.

The various anomalous groups are trying to access the 'final destination' that the ritual was supposed to reach, with different agenda. However, the 'Right Hand of Mekhane' is merely a misinformation attempt. A malevolent godlike entity was banished into the final destination millennia ago (details are unknown. Presumably it was punished for doing terrible things to humanity.) but left records of itself and the ritual that opened the passage in order to seal it. This information became gradually misinterpreted and distorted throughout history. No one knows where in the multiverse it is, including itself- it waits for someone to use the designed ritual to open a passage for its return.

While drawing close to the final destination, the Foundation is informed by a an ancient Earth-based sect of the Serpent's Hand of the truth behind the anomaly (the other groups want to access the anomaly, so they are unwilling to heed the warning). However, they are too late to stop it, as enemy agents have already opened the passage to the final iteration and unleashed the entity into Earth. Technology may have advanced significantly since the time it was banished, but the entity is still powerful and hellbent on revenge. With godlike reality bending powers, it gradually brings ruin to the world.

DESCRIPTION OF THE ENTITY
It appears as a vaguely humanoid void through which you can see the universe under normal circumstances, but its 'body' changes as it alters its surroundings. The landscapes it form are surreal, spontaneous and logic-defying, with great variety among them. For example, it can suddenly turn into a giant mountain of armor-plated crystal and mirror shards, which then expand and grow into its surrounding area, consuming enemies and structures. Or it becomes a hole out of which hundreds of tons of sea water is expelled, alongside a myriad of deadly aquatic creatures.

As this entity has some mind-reading/precognition powers, it should be able to gauge the strengths and weaknesses of each enemy, so each GOI would have a significantly different threat to deal with.

In the COTBG battle, it might become a mountainous flesh beast made from the fused bodies of millions of humans and animals. During this time, the surrounding landscape turns corrosive and electrical signals are somehow disrupted. The more scientific organisations would encounter a hallucination-like landscape with low Humes, where it's impossible to tell apart illusion from reality.

(However, take into account that its form targets the powers of a specific enemy and consider that the SCP Foundation possesses countless anomalies that do not follow any sort of pattern or logic.)

What's worse is that it learned of the locations of various powerful Thaumiel SCPs (and the equivalent for other GOI) around the world, and begins on a journey to destroy them all. The anomaly is then reclassified to Apollyon.

With their secret weapons laid bare and the fate of the world at stake, the various groups agree to collaborate in repelling the entity despite their conflicting agenda.

The allied groups of Earth throw everything in their power at it to no avail- Scranton Reality Cannons that do little to stabilise the entity’s effect, clockwork legions directed by AI hive minds that are swatted aside like flies, state-of-the-art anatech that are instantly reduced to debris… When all hope seems lost, the Serpent's Hand sect reemerges, claiming to have finally found a way to defeat the entity in the Wanderer's Library, which might involve the Foundation utilising anomalies in their containment (682?). Using this information, the groups eventually defeat and kill the entity.

As the crisis is over, the alliance is dissolved. Afterwards, consensus normality and the Veil is restored. Some sort of pact is formed between the more agreeable factions to reduce the chances of this occurring again.

The file ends with a revised version released to the general Foundation public (the full file is limited to the O5s), stating the anomaly to be Keter and then Neutralised. Containment procedures consist of isolating and monitoring the affected region. The file itself is expunged of information regarding the massive destruction that the entity caused, as well as of the multi-GOI alliance. Instead, it lists only the GOC as the Foundation's ally in the battle against the entity, which is simply described as a particularly strong reality bender.

ALTERNATE ENDING:
The Veil is broken for good due to the massive destruction the war caused and the irreversible effects of the entity upon the reality of Earth. The file ends with a letter from O5-1 warning the Foundation of what is to come. All involved groups have suffered heavy casualties, including the Foundation which lost numerous sites and Thaumiel-class objects. The anomalous world is exposed to the public and weakened against any upcoming threats. The future is uncertain.

SCP-QQ: Break the World

(Memetic kill agent warning. O5 access granted.)

Item #: SCP-QQ

Object Class:Keter Apollyon

Former Special Containment Procedures (02/05/1999): There is no feasible way to prevent the performance of SCP-QQ-1 and the subsequent occurrence of Event-QQ 'Shattered Mirror'. The landscape within SCP-QQ-2 is to be monitored for any aberrant iterations as a result of SCP-QQ-1, and the area is to be isolated under cover story WLS-48 'Nuclear Waste Disposal Site.' Efforts to negotiate and dissuade Groups of Interest involved in the activation of Event-QQ 'Shattered Mirror' are ongoing.

Revised Special Containment Procedures (13/01/2019):

Description: SCP-QQ-1 is a ritual that exchanges a set geographical region in [country] (SCP-QQ-2) with an instance of equal area from an alternate reality, an occurrence designated as a QQ 'Shattered Mirror' event.

A ritual that switches a set area on Earth with that from an alternate reality, resulting in many strange, whimsical and sometimes hellish alien landscapes (photomanipulations for stronger imagery). With each iteration, the performers draw closer to their target, and thus the landscapes are more alien and display more of the entity's influence.

The COTBG learnt from ancient scriptures that the 'end location' holds the Right Hand of Mekhane, a crucial and powerful fragment of their god. The Foundation obtained this information from a raid on a COTBG sect while they were performing the ritual, and then the knowledge was leaked to other GOI as well.

Addendum:
(GOI format) COTBG scriptures about the anomaly.
(Interview log) Alternatively, interrogation of a captured COTBG member who explains it.

Addendum:
(Report) The Foundation and the GOC's meeting and subsequent agreement to cooperate against the other factions who want to obtain the anomaly.

These groups are all trying to access the 'end location' that the ritual was supposed to reach, with different agenda. However, the Right Hand of Mekhane is merely a misinformation attempt. A powerful reality bender was sealed away in the end location millennia ago, but left records of itself that became gradually misinterpreted and distorted throughout history. No one knows where in the multiverse it is, including itself- it waits for someone to use the designed ritual to open a passage for its return. While drawing close to the end location, the Foundation is informed by a an ancient Earth-based sect of the Serpent's Hand of the truth behind the anomaly (the other groups want the anomaly, so they are unwilling to heed the warning).

Addendum:
(Interview log) The individual is taken into a Foundation site near the anomaly and warns them with great urgency. However, disaster strikes before the interview can be completed.

The Foundation is too late to stop it, as enemy agents have already opened the passage to the final iteration and unleashed the entity into Earth.

Addendum:
(Incident log) Initial description of the entity emerging and destroying personnel and structures in its vicinity.

What's worse is that it learned of the locations of various powerful Thaumiel SCPs (and the equivalent for other GOI) around the world, and begins on a journey to destroy them all. The anomaly is then reclassified to Apollyon. With their secret weapons laid bare and the fate of the world at stake, the various groups agree to collaborate in repelling the entity despite their conflicting agenda.

Addendum:
(Event log) The meeting between multiple GOI leaders. Disagreements and hostilities arise but in the end, they grudgingly agree to work together.

The allied groups of Earth throw everything in their power at it to no avail.

Addendum:
(Proposal to O5 Council) The project director asks to use experimental technology- Scranton Reality Cannon prototypes as SRA's are the only weapons to slow the entity so far, and Antimemetic Agents to conceal the massive destruction caused by the war in advance and prevent public intervention, without resorting to amnestics afterwards.

Addendum:
(Action log) Battles fought between the entity and other groups not mentioned yet- CI, MC&D, Sarkics, and perhaps even Oneiroi (if the entity kills a person whose mind hosts a major part of Oneiroi? Unlikely to add at this point)

When the entity looms over SCP-2000 and all hope seems lost, the Serpent's Hand sect reemerges, claiming to have finally found a way to defeat the entity in the Wanderer's Library. This might involve the Foundation utilising anomalies in their containment (682 as it's invulnerable to reality warping?). Using this information, the groups eventually defeat and kill the entity.

Addendum:
(Action log) FINAL BATTLE

As the crisis is over, the alliance is dissolved.

Addendum:
(After action report) Summary of the damage, actions taken, records of assistance from other groups, recovery and reconstruction of destroyed anomalies and sites.

Afterwards, some sort of pact can be formed between the more agreeable factions to reduce the chances of this occurring again.

Addendum:
(Document of the pact) Signed by the O5 Council, D.C. Al Fine, Bumaro and other leaders.

(End O5 section)

Revised SCP file listing the anomaly as Keter and then Neutralised. Containment procedures consist of isolating and monitoring the affected region. The file itself is expunged of information regarding the massive destruction that the entity caused, as well as of the multi-GOI alliance. Instead, it lists only the GOC as the Foundation's ally in the battle against the entity, which is described as a simple reality bender.

(In reality, this entity was devised by L.S. of the Serpent's Hand, who found the entity and decided to use it to weaken enemy groups. As the SH is not primarily Earth-based, they will be largely unaffected. However, their plan was foiled by a unit that decided to rebel when they learnt of the plan as they did not want the world destroyed.)

Item #: SCP-QQ

Object Class:Keter Neutralised

Special Containment Procedures: SCP-QQ-2 has been cleared of all anomalously-generated structures and vegetation. The area is to be monitored for possible re-continuation of anomalous activity.

Description: SCP-QQ-1 is a ritual that exchanges a set geographical region in [country] (designated SCP-QQ-2) with an instance of equal area from an alternate reality.

ALTERNATE ENDING:
The Veil is broken for good due to the massive destruction the war caused and the irreversible effects of the entity upon the reality of Earth. The file ends with a letter from O5-1.

Addendum:
(Letter) O5-1's message on the current situation- all involved groups have suffered heavy casualties, including the Foundation which lost numerous sites and Thaumiel-class objects. The anomalous world is exposed to the public and weakened against any upcoming threats. The future is uncertain.
